A composite disc rotor includes a disc main body, a coupling bracket and coupling units. Each of the coupling units includes a bobbin, a clip and a coupling bolt. A head part of the bobbin includes a torque receiving portion inserted in the notch and a projection projected in a circumferential direction from an end of the torque receiving portion. A pipe part of the bobbin is extended from the head part and is fitted in a coupling through hole of the disc main body. The clip includes a connecting portion between the torque receiving portion and the notch and a pressing portion extended from the connecting portion between the head part and the coupling bracket. The coupling bolt is inserted into each of through hole of the bobbin to fix the coupling bracket to the coupling unit.

A test apparatus for testing semiconductor integrated circuits includes a test head, a probe card holder for detachably holding a probe card that probes a semiconductor device, a heater for heating the probe card, and a heater holder that holds the heater in direct contact with the probe card when the probe card is held by the probe card holder. The test apparatus heats the probe card efficiently and thereby reduces test time and cost.

A semiconductor package includes a substrate for mounting and fixing a semiconductor chip thereon and a connecting pattern. The substrate is provided with an elongate opening formed therein. The semiconductor chip is fixed with its surface being mounted on the substrate and with its electrode being aligned within the elongate opening. The electrode of the semiconductor chip is electrically connected to the connecting pattern via wires through the elongate opening. The elongate opening and the wires are sealed with resin.

The pad clipis arranged between pinsmade to bridge an outer body portion and an inner body portion constituting a caliper and the two pads. An engaging plate portionis engaged with the respective pinswithout play. Press piecesformed by folding to bend both end portions in a rotational direction of the engaging plate portion in directions in which the more proximate to the two pads, the more directed to an outer side in a radial direction are brought into elastic contact with outer peripheral edges of both end portions in a rotational direction of pressure platesof the two pads. Thereby, amounts of projecting portions in correspondence with the respective press piecesin a state of a material plate before being folded to bend from the engaging plate portioncan be restrained.

Pad clip for disc brake

First to third inner locking piecestoare provided at both ends of an inner shim platein a radial direction of a rotor so as to be bent toward the pad, respectively. First to third outer locking piecesandare provided at both ends of an outer shim platein the radial direction of the rotor so as to be bent in the same direction as the locking piecesto. An inner shim plateis mounted on a pressure plate, and the first to third outer locking piecesandare superimposed on the first to third inner locking piecestosuch that main body partsandof the respective shim platesandare locked in the pad in the axial direction of the rotor.

A file access system includes a file opening unit which opens a given file within an external storage device when a file opening request is issued by an application program. A determining unit determines whether a given file within the storage device has encrypted data when a reading request is issued by the application program. When the given file is determined as having the encrypted data, a reading unit receives a fixed length of the encrypted data from the given file and generates a block of decrypted data of the same size as the fixed length by performing a decryption wherein a position of the fixed length of the decrypted data is determined by a position indicated by the reading request.

The malfunction of a vibrator as a drawback of a conventional independent vibrator type portable terminal is obviated. A communication system of a portable communication terminal comprises a portable communication terminal capable of movably communicating with another communication terminal via radio communication with a base station, and peripheral equipment which performs a predetermined operation via radio communication with the portable communication terminal. The portable communication terminal transmits a radio signal to the peripheral equipment by using a time division multiplex access system for exchanging signals by putting data on a time slot as the radio communication between the portable communication terminal and the peripheral equipment and using the time slot in a time zone excluding other time zones in which the portable communication terminal is transmitting a radio signal to the base station. Thus the radio wave transmitted from the portable communication terminal to the peripheral equipment is prevented from being jammed by the radio wave transmitted from the portable communication terminal to the base station.
